How to Compare Sodium Vapor Lights

There are high-pressure sodium lights, which are more expensive and consume more energy, and low-pressure sodium lights, which are cheaper, but take up to 10 minutes to start and offer very poor color resolution. Comparing sodium vapor lights isn't difficult, but it does require you to examine the lights carefully to decide which is better for your purpose. Does this Spark an idea?
